Generator AVR SX460 Automatic Voltage Regulator
SX460 is a half-wave phase-controlled thyristor type Automatic Regulator(avr) and forms parts of the excitation system for a brushless alternator.
In addition to regulating the alternator voltage, the voltage regulator circuitry includes under speed and sensing loss protection features. Excitation power is derived directly from the generator terminals. Positive voltage build up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR. The automatic regulator AVR is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulation of +/-1.0%.
In addition to being powered from the main stator, sx460 also derives a sample voltage from the output windings for voltage control purposes. In response to this sample voltage, the AVR controls the power fed to the exciter field, and hence the main field, to maintain the machine output voltage within the specified limits, compensating for load, speed, temperature and power factor of the alternator.
